I've been thinking about rewiring my Tekton Lores with the 18gauge Teflon coated silver hookup wire on sale right now at Parts Connexion. I believe the stock wire is 14 gauge stranded zip cord.

 I know silver has less resistance than copper. Does this mean you can get by with thinner wire for the same purposes?  What about solid core vs stranded? I can't seem to easily find any charts online for gauge for given power/watts that specify silver.

The Lores are rated at around 200 watts I believe, and I have a 200 watt amp I sometimes use, but they're also high efficiency at 96+ db and very unlikely to use more than 10-20 watts even at very high volume listening. 

I'm just concerned about what might be sacrificing at the extreme edge of performance and also what I would need to tell a prospective buyer if I ever intended to sell them.

I recall that it's about one AWG different.
That is 14AWG copper = 15AWG silver.

Not enough difference between solid and stranded to think about. It probably varies more brand to brand than solid to stranded.

It's not a question of wattage.  You could run 200 Watts of music through 24AWG copper all day at it wouldn't even get warm.  I'm saying that you could not that you should. (never saw any power tests on silver)

If it's not a question of power, then what is the parameter that matters?

The most obvious parameter is how much the wire costs.  The higher the cost the better, obviously. 

The second more necessary parameter is "is the wire long enough to reach without making splices?"

Third, for longer runs is total end to end resistance.

For long runs high resistance can act as a voltage divider that varies with frequency.
